Abstract

rolo de moagem. a presente revelação se refere a um rolo de moagem que compreende um corpo de rolo tendo uma superfície cilíndrica externa que se estende axialmente entre um par de extremidades opostas, e um sulco lateral formado em cada extremidade do corpo de rolo, sendo que o sulco lateral inclui um ombro de suporte rebaixado a partir da superfície cilíndrica externa e/ou a partir de superfícies das extremidades opostas do corpo de rolo. o rolo de moagem compreende adicionalmente um anel de borda incluindo uma pluralidade de cavidades receptoras espaçadas, e uma pluralidade de membros de desgaste, sendo que cada membro de desgaste é recebido e retido em pelo menos uma das cavidades receptoras do anel de borda. os membros de desgaste estão posicionados ao longo do anel de borda para definir uma borda do rolo de moagem, e o anel de borda é recebido dentro de cada sulco lateral. a pluralidade de membros de desgaste está disposta para fornecer uma superfície de proteção contra desgaste que é angulada em relação à superfície cilíndrica externa do corpo de rolo. o fornecimento de uma superfície angular protetora contra desgaste evita o acúmulo excessivo de material no rolo de moagem e reduz a necessidade de manutenção. também são revelados uma montagem de moagem e um segmento de anel de borda que fornece maior proteção contra desgaste.grinding roller. The present disclosure relates to a grinding roller comprising a roller body having an outer cylindrical surface extending axially between a pair of opposite ends, and a lateral groove formed at each end of the roller body, the lateral groove being includes a support shoulder recessed from the outer cylindrical surface and/or from opposite end surfaces of the roller body. the grinding roller further comprises an edge ring including a plurality of spaced receiving cavities, and a plurality of wear members, each wear member being received and retained in at least one of the receiving cavities of the edge ring. wear members are positioned along the edge ring to define an edge of the grinding roll, and the edge ring is received within each side groove. the plurality of wear members are arranged to provide a wear protective surface that is angled with respect to the outer cylindrical surface of the roller body. Providing a wear-protective angular surface prevents excessive material build-up on the grinding roller and reduces the need for maintenance. Also disclosed are a grinding assembly and an edge ring segment that provides greater wear protection.
